Please make sure you do report any bugs.Any suggestions to improve the design or the code are welcome.The idea is to be able to provide cheaper and reliable rocketry payload.

Before your startRemember that those are kits and that you can modify the program and behaviour of those kits.The country where you live might not even allow the use of such device. You have to assume total legal responsibility for any damages or claims including personal injury that results from the use of those devices.I shall not be responsible for the above. If you disagree with that, please do not build them or use them.

I can provide kits at a reasonable price (I am hardly making any profit... prices start at 15 euros a kit which is about 20 USD)

I will not build the kit for you: you will have to solder everything yourself.
